Original Abstract Submitted
A noise reduction circuit includes a surface-mount common mode choke coil mounted on a circuit board. Output terminals of the common mode choke coil are connected to an input capacitor via second circuit patterns. Two terminals of the input capacitor are connected to two input ends of a switching circuit via third circuit patterns. Path lengths of the second circuit patterns are longer than path lengths of the third circuit patterns. Of a plurality of current paths, the path lengths of the third circuit patterns are shortest in comparison with path lengths of other current paths. First circuit patterns are parallel and face each other to form a first parasitic capacitance, and the second circuit patterns are parallel and face each other to form second parasitic capacitances.
